摘要：The article describes the characteristics of micro-nano bubbles in the water for a long time, large specific surface area, high gas-liquid mass transfer efficiency, high interface potential and free radical generation. The generation of micro-nano bubbles is introduced, such as dissolved gas release method and dispersion. Air method, electrolysis method, etc. It mainly summarizes the research and application of micro-nano bubbles in surface water treatment, groundwater remediation, industrial wastewater treatment and enhanced ozone treatment, as well as practical applications in ship operation, metal surface degreasing and fruit and vegetable growth.
